He doesn't wear a helmet with the Indian flag on it and the reason behind it was explained by a Quora user.

Here's what he wrote:

So a wicketkeeper very often has to keep the helmet someplace back in the distance when he does not wear it. A National flag is a symbol of great honour and respect, so it can't be placed on ground as the law states. That's a true conduct, you can Google it. Hence either you don't put the helmet with Flag on ground or don't put the Flag on the helmet at all.
Dhoni chose the latter.

He is also an army officer, so he must abide by this even more religiously. Cricketers, or public figures like this are Great examples to be followed by a nation. So he is just setting a good example for everyone to follow as well.
